feat(ecommerce): tiles promocionales intercalados en el grid del catalogo

ADR 0005 seccion 3 (patron Walmart), ultimo item de la sub-fase de
componentes visuales: "grid de catalogo con tiles promocionales
intercalados, no solo tarjetas de producto homogeneas".

`category-tiles.tsx` ya era ese mismo primitivo visual (usado en el
home) -- se extrajo el tile individual a un componente exportado
`PromoTile` (mismo look, sin cambio visual en el home) para
reutilizarlo en `catalog-client.tsx`: un tile cada
PROMO_TILE_INTERVAL=8 productos, ciclando por las categorias raiz
(excluye la raiz que el usuario ya esta viendo via el breadcrumb de
#40). Si no hay jerarquia de categorias disponible, la grilla queda
igual que antes (solo productos) -- degradacion sin romper nada.

Depende de #40 (breadcrumb + categoryNodes en CatalogClient) -- mismo
archivo, se apila sobre esa rama en vez de main.
